I tend to see big tech pulling shit out their asses like this every other week. Slowly trying to gain more power of end user, where the end user has no choice but to use said product.

That is why i love open source projects and I think what you said is gonna happen. If google keeps on this negative intentions for AOSP, then for sure people will be fed up about it and fork to create their own thing. Besides, like u said, many messaging app, but i never saw a dialer app before 🤔 maybe they do exist, if not i am sure someone will create them.
